I don't think the review is as good as some others do. The cinematography is very nice, but I get soured easily with misinformation. I just don't understand, if your jobs is to do car review videos, how hard is it to get your information correct?

Can't stand it when people like this don't even take the time to read the brochures for the car they're reviewing, let alone do 30 minutes of research on the internet. I had to stop watching after 3 minutes, at least there was some nice exhaust noise by then.

What about the comment that the BMW Perf Exhaust gets louder over time and provides more power because of the sound insulation breaking down. Could that be true?

The exhaust DOES indeed get louder with time. Mine is a week old and already getting louder. My wife didn't notice the difference the day after the install, but after 4hours of driving to and from EUROFEST she asked me if I have done something different to the car. My answer was that since its spring we are rolling the windows more frequent. LOL
